This is a longshot, but I was wondering if anyone happens to have one of these old attachments for an Adams Trail-a-Bike either lying around in a garage, or maybe left on the back of a bike, which is no longer used or wanted? They don't seem to be readily available in the UK anymore, and I have a Trail-a-Bike which unfortunately can't be used until I can get this part. Happy to collect whenever convenient with you.
Thanks for reading
